AsyncTask Force Close Errors / HTTP Request To MySQL Database
Aug 22, 2012
I'm trying to connect my app to a MySQL database to retrieve data. Obviously I have to do this in a new thread hence why I chose AsyncTask, something I'm new to.
I have included Toasts to tell me if there are problems when trying to carry out any part of it. However these toasts are not showing on the UI thread. I tested this out by turning off the server my SQL database is on so that it could trip the first toast. It didn't show it though and instead it gave me a force close error. When my server is running I have no issues and although I haven't coded the bit to retrieve data yet the code below does connect to my database and at least lets me view the page "CurrentSeasonDrivers".
Here is my code and the logcat showing the errors below that:
package com.android.history;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
[code]....
All I want it to do is show a toast if the application cannot connect to the server instead of force closing.

Is there a way to notify an activity/service of a force-close request right before it gets killed?
I mean when the user hits the force close button in Menu>Settings>Applications>Manage applications>app name>Force Close.

I am trying to upload a video to an api and I was wondering how you show a progress bar show and also dismiss it when an upload has finished? Also, while were at it, do you see anything wrong with my pattern.compile for my edit boxes?
Code:
public class Loadvid extends AsyncTask <Object,Integer,String>{
EditText etxt_user = (EditText) findViewById(R.id.user_email);
EditText etxt_pass = (EditText) findViewById(R.id.friend_email);
[code]...
But it doesn't work. When i click on the button to send, it shows the handler for 2 seconds then brings up an error close.Error log.

Could someone provide the basic code to use if I want to perform a http request on android to the address "address" with the string "message" ? Also I'd like to check the server response and perform some actions if the right conditions meet , but I ' m unsure of how and when the server send back the response . My guess is that the response is gotten in a blocking function, or in an asynchronous function . Could you provide code or information on this as well ?

I have a HTTP GET request that I am attempting to send. I tried adding the parameters to this request by first creating a BasicHttpParams object and adding the parameters to that object, then calling setParams( basicHttpParms ) on my HttpGet object. This method fails. But if I manually add my parameters to my URL (i.e. append '?param1=value1¶m2=value2') it succeeds.

I am using a PHP script to convert my MySQL database data into JSON data. I am successful in doing so. Now I want to retrieve the data from my PHP script (on my localhost server) and parse that data and display it in a TextView. Everything runs fine, no errors, but the data is not displaying as I think it should. Here is my code for my MainActivity...
[HIGH]package com.example.testexternaldatabase;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.http.HttpEntity;
[code]...
I have a TextView called "result" and I gave permissions to access the internet in my manifest.

I'm trying to connect my program to a Mysql Database. The ling between my Android emulator and my server is OK, the ping is good. Moreother, I checked the connexion with a PhP script and everything is ok.
I would like to connect my program directly to the dataBase, using JDBC, et the J-connector. I added it to my project, and the code I use to etablish the connexion is :
Code:
private static final String DRIVER = "com.mysql.jdbc.Driver";
private static final String DATABASE_URL = "jdbc:mysql://10.0.2.2/annuaire";
private void initDb() {
try {
Class.forName(DRIVER);
[Code] .....
The problem is the I have an exception, and I don't know why. The fonction getConnection(DATABASE_URL,"root",""); throw the exception.Below, the screen shot with variables of the exception :

I am wanting to send a http request to Google.com from my mobile application but am unsure how to get about asembling the request. Anothing problem that i might in counter is how to handle the information that is returned. For example, i want to send a request for "local resturnats" to Google and have the results returned and then displayed to the user in a ListView. Am i going about this the right way? Is there an API that i could use (GoogleMaps or AJAX Search)?

I have a game in development that makes http calls to my server. The server handles some database interaction and returns some XML for the game to parse. The issue is that the connection seems very unreliable. I believe my server is in part to blame for this because it can be somewhat unresponsive at times, but the frequency is MUCH greater when communicating with the phone than with a browser on a computer. I also notice that it gets worse when 3G is not available for the phone and it is on the edge network. Is there any way to code my app to make it more robust? Do I need to retry calls X times on failures?
Here is the code I am using now:

I have an Android application from which I want to upload some data to a database on my web server. As the MySql java library has a size of about 5 mb, I don't want to include it with the application.So I'll make a HTTP request for a php script and send the data with the URL as parameters. How do I make sure that only I can call this? I don't want people to sniff up the URL and call it outside my application.

I'm trying to send an http request from my app to script on my website. The script simply writes the parameters received from the request. If I send the request from a browser it works, so the script is ok, but from my app nothing happens.
This is the code I'm using. The toast at the beginning is only to check if the parameters arrive correctly to the function, they are correct.
Code:
public void postData(String from, String to, String date, String time, String searchby, String type, String orderby) {
String testo = from+" - "+to+" - "+date+" - "+time+" - "+searchby+" - "+type+" - "+orderby;
Toast toast=Toast.makeText(this, testo, 6000);
[Code]....

I'd like to make an http request to a remote server while properly handling cookies (eg. storing cookies sent by the server, and sending those cookies when I make subsequent requests). It'd be nice to preserve any and all cookies, but really the only one I care about is the session cookie.
With java.net, it appears that the preferred way to do this is using java.net.CookieHandler (abstract base class) and java.net.CookieManager (concrete implementation). Android has java.net.CookieHandler, but it does not seem to have java.net.CookieManager.
I could code it all by hand by inspecting http headers, but it seems like there must be an easier way.
What is the proper way to make http requests on Android while preserving cookies?

I honestly could not think of a good title. Sorry. Anyway, so I have an app that I am making where I pull information from my custom web api. I pull data from the api and fill in the layout with this information. Problem is it takes a while so the app stalls for a few seconds before the information is pulled since it is in the onCreate method of the activity. To resolve this I implemented a loading dialog. This is where the problems began. I put the http requests into a seperate thread and it downloads fine. No problem. However it keeps force closing every time I try to modify the layout afterward. So basically my question is how do I modify the layout after the background thread is finished? Everything I try keeps force closing the app.

We have an android app that currently sends data to a php script which writes to a mysql DB on the same server. We are thinking of using a scalable remote DB e.g. amazon RDS.The question is how does our android app write to these remote DBs? Do they have some kind of rest API, or do we have to send the data to the same php script on our server but use that to post to the remote mysql DB?

I have an mysql database with some sports results in it. I want to write an android application to display these data on mobile phones.
I´ve searched on the internet for this issue and i think it is not possible to have a direct connection between the mysql database and the android application. (Is this right?)
So my question is the following: How can i have access in the android application to the mysql database in order to display some of the data?
